Definitions

  • the present disclosure relates to a barrier for a zipper assembly.
  • the barrier is used with a zipper assembly to prevent the infiltration of small particles and/or organisms from one side of a barrier to an opposite side of the barrier.
  • Bed bugs are a type of small parasitic insect that prefers to feed on human blood and that can dwell within bed mattresses.
  • a fabric cover or encasement may be provided to surround the mattress so as to prevent the bugs from escaping.
  • the encasement is typically placed around the mattress and closed by a zipper so that the bed bugs encounter the barrier of the fabric cover and are unable to exit.
  • FIG. 1A depicts a conventional zipper assembly 10 having two strips of fabric tape 40 each affixed to corresponding zipper tracks 32, 34.
  • the zipper tracks each have a number of teeth 36 that can be enmeshed together to form a set of linked zipper tracks 30.
  • a zipper slider 20, having a Y-shaped channel, is manipulated by a user pulling a tab 22 to move the zipper slider along the rows of teeth so as to bring opposing rows of teeth together into a mesh, or to separate previously enmeshed teeth.
  • the zipper can be opened or closed.
  • the zipper may be pulled in a direction (e.g., upward) so as to reach a closed position and such that the linked zipper tracks 30 may largely restrict the passage of small particles or organisms from one side of the zipper to the other.
  • a small space e.g., about 5 mm 2 in area
  • small particles or organisms might move will almost inevitably exist at the top of the zipper.
  • CN 201 839 825 U which forms the basis for the preamble of independent claim 1, relates to an insect prevention zipper coat with a magic tape arranged on two sides of a sewing part in the closing position of the zipper, and a hook surface of another magic tape that corresponds in position to that of the magic tape on the two sides of the zipper.
  • the inventors have recognized that, when closing a zipper, no matter how tightly the zipper is pulled shut, a small hole will still remain between the zipper slider and the end of the zipper tracks. This hole will often provide a passageway through which small particles or organisms are able to infiltrate or escape from one side of the closed zipper to the other. Embodiments described herein relate to the appreciation that it would be beneficial to obstruct and/or block exit from such a passageway so as to limit the migration of small particles or organisms.
  • Zipper assemblies include a zipper slider for manipulating a pair of zipper tracks between open and closed positions of the zipper assembly and may be used with the present barrier that is engageable with the zipper slider resulting in an obstruction that blocks migration of small particles and/or organisms through regions of the zipper assembly or from one side of the zipper or the barrier to another.
  • the barrier includes a base having a base surface that is attachable to an article, for example, a padding or bedding material (e.g., mattress/pillow cover) or bag/luggage, that is opened and closed by the zipper.
  • the barrier includes a slider connecting region comprising a recess constructed to receive an appropriate connection portion of a zipper slider (e.g., a front piece of the zipper slider, the zipper slider itself, etc.) upon closing of the zipper assembly.
  • an obstruction is formed by the connection between the barrier and zipper slider, preventing the migration of small objects such as bed bugs, other organisms or particles from one surface of the barrier to an opposite surface of the barrier (e.g., between upper and lower regions of the barrier).
  • Barriers described herein may be used for articles for bedding arrangements (e.g., mattress/pillow covers, duvets, comforters, sleeping bags, etc.) or other padding materials that are opened and closed by a zipper.
  • bedding arrangements e.g., mattress/pillow covers, duvets, comforters, sleeping bags, etc.
  • other padding materials that are opened and closed by a zipper.
  • bed bugs may be prevented from migrating through the small opening that is commonly present in the zipper assembly between the zipper slider and the end of the zipper tracks.
  • a barrier according to claim 1 is provided.
  • the protective assembly includes a pair of zipper tracks including a first plurality of teeth engageable with a second plurality of teeth; a zipper slider constructed and arranged with the pair of zipper tracks to manipulate the pair of zipper tracks between an open position and a closed position, and a barrier according to the invention.
  • aspects discussed herein relate to a protective barrier at the end of a pair of linked zipper tracks of a zipper assembly so as to obstruct the migration of small particles and/or organisms from one side of the barrier to the opposite side of the barrier when the zipper assembly is closed.
  • traditional zippers incorporated on an article e.g., padding material, mattress/pillow covers, duvets, comforters, etc.
  • a narrow opening at the end of the zipper tracks will almost invariably remain.
  • Such an opening may be large enough (e.g., between about 1 and 10 mm 2 ) for small organisms such as bed bugs and/or dust mites to migrate or crawl through the passageway provided by the narrow opening and move freely from one side of the article to the other.
  • embodiments of protective assemblies described herein may provide certain advantages by being constructed in a manner that creates an obstruction that blocks or minimizes openings which commonly remain at the end of a closed zipper and, thus, prevents or reduces the migration of particles and/or organisms between opposite sides at the end of the zipper. Therefore, when the zipper is closed, small particles or organisms can be substantially prevented from migrating freely from an interior region of the article to the exterior (or vice versa).
  • a barrier in all embodiments, includes a base surface that may be attached to a suitable article (e.g., padding material such as fabric for use in a bedding or furniture arrangement).
  • a particular region of the barrier is suitably adapted to form a connection with a portion of a zipper slider upon closing of the zipper assembly.
  • Such a connection results in the formation of an obstruction, which can inhibit movement of small objects such as allergens, particles, dust mites, bed bugs and/or other organisms between opposing surfaces of the barrier (and, for example, the fabric) proximate to the zipper slider and at the end of the linked zipper tracks of the zipper assembly.
  • the barrier is configured as a plug where a portion of the barrier has a structural feature that engages with a complementary structural portion of a zipper slider to form an obstruction by the resulting connection with the zipper slider.
  • the barrier includes a cover that engages with at least a portion of a zipper slider to create a suitable obstruction.
  • the zipper slider may form a flush connection with the base and the cover may enclose the zipper slider and a portion of the zipper tracks to establish one or more obstructions that prevent the migration of particles/organisms past a portion of the barrier (e.g., past a base portion of the barrier or between upper and lower regions of the barrier).
  • placing the zipper assembly in a closed position may result in a suitable connection between an appropriate barrier and a zipper slider that is free of openings greater than a certain amount of surface area.
  • such a connection between a barrier and a zipper slider may be free of openings that are greater than 20 mm 2 , greater than 10 mm 2 , greater than 5 mm 2 , or greater than 1 mm 2 in surface area.
  • connection between the barrier and zipper slider may prevent the escape of particles or organisms from underneath the barrier (or base of the barrier) to above the barrier (or base of the barrier), or vice versa.
  • the zipper slider may be pressed against a portion of the base so that the zipper assembly itself is closed, and the cover may be brought over the top of the zipper slider so as to form a press fit or snap fit with the base.
  • Appropriate material e.g., foam, plastic, polymer, cushioning, padding
  • Such an arrangement may form one or more suitable obstructions that prevent the migration of particles or organisms from one side of the barrier to the other.
  • a suitable connection between the barrier and zipper slider may obstruct migration of particles/organisms between different regions (e.g., upper and lower regions) of the barrier where the particles/organisms are less than 5 mm, less than 1 mm, less than 100 microns, less than 50 microns, less than 10 microns, or less than 1 micron in size.
  • FIG. 1B illustrates a mattress cover 400 that provides a protective encasement for a mattress " M .”
  • the mattress cover 400 may include a zipper assembly 100 for use in separating or joining together different fabric portions of the cover.
  • mattress covers may include protective assemblies having a zipper and a barrier disposed on a portion of the mattress cover that can engage with a corresponding zipper slider to provide an appropriate obstruction upon connection. Such a connection can provide a suitable obstruction that, for example, effectively blocks bed bugs, dust mites, allergens and/or other small particles from entering and exiting the mattress cover.
  • Suitable articles described herein may be useful for any purpose where zippers are used, such as for mattress covers, encasements, pillow covers, linen sheets (e.g., duvets, comforters, etc.), padding materials, curtains, drapes, protective coverings (e.g., for swimming pools, tubs, etc.), outdoor equipment (e.g., tents, jackets, etc.) articles of clothing, luggage, carrying cases, suitcases, bags (e.g., gym bags, backpacks, etc.), or any other suitable application.
  • Suitable materials for the articles may include, for example, fabric, plastic, polymer, or any other appropriate material.
  • portions of padding/bedding material or another appropriate article may be attached to respective zipper tracks and may be suitably joined together or separated depending on whether the zipper slider is manipulated into an opening or closing direction.
  • the barrier includes a base surface 512 that can be appropriately attached to the article via any suitable fastening arrangement.
  • the barrier can be attached to the article at a suitable location on the article proximate the end of the zipper assembly so that the barrier may be in position to form an obstruction by the connection with the zipper slider when the zipper assembly is closed.

  • the base surface of the barrier may include one surface of a hook and loop fastener arrangement (e.g., hooks) and an appropriate location on the article may include a complementary surface of the hook and loop fastener arrangement (e.g., loops).
  • a zipper assembly and appropriate article is arranged to include a protective barrier attached to the article that may provide suitable blockage of small particles and/or organisms between interior and exterior surfaces of the article that extend beyond the barrier
  • the zipper may be inadvertently left open.
  • a situation may arise where a user pulls the tab 122 to close the zipper and even though the zipper slider is moved in close proximity to the barrier, a preferred connection or engagement between the zipper slider and the barrier is not made; that is, for some embodiments, the zipper slider is not adequately engaged with or "plugged" into the barrier and a proper obstruction between the zipper slider and the barrier preventing small particle/organism migration from one side of the barrier to an opposing side is absent.
  • embodiments described herein may also include a notification system that produces a notification signal to a user upon proper connection of the zipper slider and the barrier.
  • a notification member when the slider connecting region of the barrier and the barrier connection portion of the zipper slider are connected so as to form an appropriate obstruction that prevents migration of small particles and/or organisms, a notification member produces an appropriate signal (e.g., audible, visual, tactile, etc.) that informs the user that the zipper is adequately closed and that the zipper slider and barrier are suitably connected.

  • a user manipulates the cover 560 relative to the base 510 (e.g., grasping the tab, pushing against the exterior surface of the cover, etc.) so that surfaces 512, 562 come into contact with one another.
  • the cover 560 and base 510 are mutually attached via a snap fit configuration.
  • the upper padding 570 may engage with the zipper tracks at the rear side of the zipper slider to provide a seal-like arrangement to further obstruct migration of small particles and/or organisms.
  • FIG. 14 illustrates the barrier closed over and enclosing the zipper slider and zipper tab, further securing the zipper assembly in a closed configuration where particles and/or organisms are restricted or prevented from migrating from beneath the barrier, out of the barrier, and back.
  • the upper padding 570 is disposed at the rear of the zipper slider and engages the zipper tracks to block migration of small particles and organisms.
  • the first padding surface 572 resides against the closed zipper tracks located within the barrier, the second padding surface 574 comes into flush contact with upper surfaces 524, and the third padding surface 576 comes into flush contact with side surfaces 526. Accordingly, small particles and/or organisms are prevented from migrating between an interior and an exterior of the article (e.g., bedding/padding material) past surfaces of the barrier and/or zipper slider that are in contact with one another. In the embodiment, small particles and/or organisms are prevented from migrating past a base portion of the barrier. In the embodiment, small particles and/or organisms are prevented from migrating past surfaces between a base and a cover of the barrier that are in contact as well as surfaces between the zipper slider and the barrier that are in contact.
  • the article e.g., bedding/padding material
  • FIGS. 15A-18B illustrate operation of another embodiment of a barrier 500.
  • the barrier may be used with a zipper assembly and appropriate article (e.g., bedding/padding materials) for obstructing the migration of particles and/or organisms from one side of the barrier to an opposite side when the zipper assembly is placed in a closed position.
  • the base 510 includes a slider connecting region 540, provided as a recess or cutout space within which the zipper slider may reside when the zipper assembly is placed in a closed position.
  • a user may pull the zipper tab 123 toward the barrier along the direction indicated by the arrow shown in FIG. 15A .
  • the slider padding 542 of the slider connection region 540 extends into the recess and may be deformable such that when the zipper slider pressed up against the padding, the padding conforms to the shape of the front portion of the zipper slider. When pressed against one another, a snug fit is formed between the slider and the padding so as to obstruct migration of small particles/organisms through the recess between the slider and the padding.
  • the slider connecting region 540 includes detents 523 that may resist movement of the zipper slider by virtue of their protrusion into the slider as the slider moves relative to the detents, forward or backward through the connecting region 540. That is, for some embodiments, to move the zipper slider past the detents for closing the zipper assembly, a user may need to pull the zipper tab or push the zipper slider with slightly more force than would otherwise be necessary for moving the slider along other regions of the zipper tracks.
  • FIG. 16 illustrates the zipper slider pressed up against the padding 542 where some extra effort may have been exerted for the slider to move past the detents 523.
  • the zipper tab may be placed into engagement with the post 530 similarly to that shown and described for FIG. 13 .
  • the zipper tab 122 may optionally be placed within the receiving region 520 and rest secured where the tab remains substantially parallel with respect to the base of the barrier.
  • the upper padding 570 of the cover 560 extends outside the boundary defined by the surface 562. For instance, a portion of the padding 570 is adhered to the inner surface of the cover and another portion of the padding spills out past edges of the cover extending toward the tab 564.
  • the cover 560 may be brought toward the base 510 in the direction indicated by the arrow shown in FIG. 17 so as to close the barrier.
  • the cover 560 and the base 510 are suitably fastened to one another (e.g., interference fit, snap fit).
  • FIGS. 18A-18B illustrate a closed barrier where the cover encloses the zipper slider and tab.
  • the padding 570 substantially surrounds the rear of the zipper slider and presses against the zipper tracks.
  • a first padding surface 572 that extends outside the cover and toward the cover tab 564 may be pressed down against the zipper tracks and a second padding surface 574 that remains within the space enclosed by the cover may be pressed down against the zipper slider and tab.
  • the padding 570 creates an additional obstruction that blocks migration of small particles/organisms past the barrier 500.
  • the zipper tab 122 when the barrier is closed, the zipper tab 122 is appropriately placed in a resting position within the receiving region 520 and enclosed by the cover. Accordingly, when placed in this resting position, the zipper tab 122 does not interfere with the obstruction formed by the padding 570 along the zipper tracks.
  • an appropriate indication may be provided so as to notify an inspector that the barrier is properly installed in creating the suitable obstruction(s).
  • Such an indication will allow a person to determine with confidence that small organisms or particles are prevented from migrating from the space enclosed by the article (e.g., bedding, padding, bag) to the exterior surface of the article and outside the barrier, or vice versa. If, for example, someone who is inspecting whether the zipper assembly and the barrier are both properly closed and installed is not able to receive notification of such an indication, then the zipper assembly and/or barrier would have to be further manipulated to so that the appropriate obstruction(s) are formed.
  • the cover has a window 590 that is transparent or translucent, allowing for an inspector to view through the window 590 whether the zipper tab is appropriately placed.
  • FIG. 18A illustrates a zipper and barrier that are properly closed where the tab 122 is visibly shown through the window 590.
  • the window may be a separate element or the material itself that forms the device.
  • the cover 560 may be comprised of a transparent or translucent material where the window and the cover are one in the same. That is, in this embodiment, the window is an integral part of the cover.
  • the window is formed as a separate material apart from the cover and joined with other components to form the cover through a suitable manufacturing process.
  • the zipper tab is optionally colored in a manner that provides a visual contrast with the rest of the device and allows the inspector to easily see whether the zipper tab is suitably in place (e.g., zipper tab may be bright green, red, blue, yellow, etc.).
  • zipper tab may be bright green, red, blue, yellow, etc.
  • an inspector may have a need to quickly determine whether the barrier is appropriately installed for a large number of bedding encasements (or other appropriate articles).
  • a window in the cover and a visually contrasting zipper tab an inspector can quickly peer through the window and see whether the zipper tab is suitably placed in its appropriate resting position. Accordingly, the inspector can confidently move on to the next article knowing that beg bugs or dust mites will be prevented from migration from the interior to the exterior of the encasement, and back.
